“A history of civilization shares the presumptuousness of every philosophical enterprise: it offers the ridiculous spectacle of a fragment expounding the whole. Like philosophy, such a venture has no rational excuse, and is at best but a brave stupidity; but let us hope that, like philosophy, it will always lure some rash spirits into its fatal depths.”

“To ridicule philosophy is really to philosophize.”

“Philosophy begins in wonder. And at the end when philosophic thought has done its best the wonder remains.”

“That philosophy died yesterday, since Hegel or Marx, Nietzsche, or Heidegger—and philosophy should still wander toward the meaning of its death—or that it has always lived knowing itself to be dying... that philosophy died one day, within history, or that it has always fed on its own agony, on the violent way it opens history by opposing itself to nonphilosophy, which is its past and its concern, its death and wellspring; that beyond the death, or dying nature, of philosophy, perhaps even because of it, thought still has a future, or even, as is said today, is still entirely to come because of what philosophy has held in store; or, more strangely still, that the future itself has a future—all these are unanswerable questions. By right of birth, and for one time at least, these are problems put to philosophy as problems philosophy cannot resolve.”

“Let animals live like animals; let humans live like humans. That's my whole philosophy in a sentence.”

“Every theory of social action is ultimately a philosophy of history. It attempts, as best it may, to read in the experience of mankind the lessons which would justify its own special urgency.”
